This delicious, easy-to-make creamy scalloped potatoes recipe is baked in a tasty cheese sauce until golden brown. These will become your new favorite side dish after trying them.
Scalloped potatoes are a delicious potato casserole dish where layers of thinly sliced potatoes are cooked with butter, cream, or milk and then baked until done. This recipe uses butter which I feel gives the perfect combination of crispiness on top and creaminess towards the bottom of the pan.
It’s incredibly hard to find the origin of scalloped potatoes but what I did find was that there is an old English word, “collops,” which means meat slices. Collops are also related to the French word escalope.
The word Collops over time, came to mean slices, which were usually thick. In the city of Yorkshire, there was a dish called “collops,” which were thick slices of potatoes cooked until brown.
Ingredients to Make Scalloped Potatoes
- Potatoes – I used russet potatoes, but you can use Yukon gold or red bliss potatoes.
- Onions – A yellow onion works well, but a white or sweet onion will work as well.
- Garlic – Just 1 minced clove of garlic will go a long way in the flavor department.
- Butter – Always use unsalted butter in your cooking and baking.
- Flour – All-purpose flour works perfectly for this.
- Milk – I prefer to use whole milk, but you can substitute with half and half, or even heavy cream.
- Cheese – I used a combination of parmesan and asiago cheese.
Follow these simple-to-prepare procedures to make these Scalloped Potatoes:
Brown some onions in a medium size pot over medium heat.
Stir in garlic and cook just until fragrant.
Mix in some all-purpose flour to make a roux.
Next, pour in the milk and bring it to a boil over high heat until it becomes thick.
Finish by stirring in cheese, salt, and pepper.
Add some cheese sauce to the bottom of a prepared casserole dish.
Layer on with half the potatoes, cheese, and sauce. Repeat the process ending with cheese.
Bake in the oven at 350° for 1 hour or until well browned on top and tender. Serve.
